摘要： An aqueous coating fluid is described comprising gelatin at a concentration of at least 1 wt % and gelatin hardener at a level from 1-200 effective &mgr;mole hardener per gram of coating fluid, wherein at least 20% of the gelatin comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide. Relative improvements are obtained in reducing the rate of chemical gelation of a coating fluid containing gelatin and a hardener, without the need for chemically modifying functional groups of the gelatin. The invention further enables an increase in coating fluid concentration, increase in the fluid viscosity, reduction in the ratio of added anionic polymer to gelatin, and/or increase in the pH of a coating fluid containing gelatin and a hardener, without detrimentally increasing the rate of chemical gelation of the coating fluid. The invention also enables the inclusion of relatively more reactive hardeners in a coating fluid containing gelatin, and/or the inclusion of relatively higher molecular weight gelatin in a coating fluid containing hardener, without detrimentally increasing the rate of chemical gelation of the coating fluid. Each such advantage may be achieved either individually, or in combinations to varying extents.

摘要： An imaging element is described comprising one or more hydrophilic colloid layers which include gelatin as a film forming binder which has been chemically crosslinked with a gelatin hardener, wherein at least 20% of the gelatin of at least one of the one or more hydrophilic colloid layers comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide, and the gelatin is chemical crosslinked with a gelatin hardener at a level from 70 to 120 effective &mgr;mole hardener per gram of gelatin. Improvements are obtained in the wet mechanical strength of an imaging element comprising gelatin as a binder, without needing to increase the amount of chemical crosslinker with respect to the gelatin. The invention further enables the use of relatively low molecular weight gelatins without compromising the wet mechanical strength of imaging elements and without needing to increase the amount of crosslinker relative to the amount of gelatin. The invention also enables the selective improvement in the wet mechanical properties of layers with a high ratio of non-binder materials to binder without substantially increasing the amount of chemical crosslinker.
